After update to macOS 10.13.3
After updating do macOS 10.13, I had to install "Command Line Tools (macOS 10.13) for Xcode 9.3" downloaded from https://developer.apple.com/download/more/
Check your server config file /etc/mysql/my.cnf
- verify bind_address
is not set to 127.0.0.1
. Set it to 0.0.0.0
or comment it out then restart server with:
sudo service mysql restart
Also you can setup extJs writer
with encode
: true
and it will send data regularly (and, hence, you will be able to retrieve data via $_POST
and $_GET
).
... the values will be sent as part of the request parameters as opposed to a raw post (via docs for encode config of Ext.data.writer.Json)
UPDATE
Also docs say that:
The encode option should only be set to true when a root is defined
So, probably, writer
's root
config is required.
Within your onDropDownChange
handler, just make a jQuery AJAX call, passing in any data you need to pass up to your URL. You can handle successful and failure calls with the success
and error
options. In the success
option, use the data contained in the data
argument to do whatever rendering you need to do. Remember these are asynchronous by default!
function onDropDownChange(e) {
var url = '/Home/Index/' + e.value;
$.ajax({
url: url,
data: {}, //parameters go here in object literal form
type: 'GET',
datatype: 'json',
success: function(data) { alert('got here with data'); },
error: function() { alert('something bad happened'); }
});
}
jQuery's AJAX documentation is here.
Just like you said
select * from tbl where statusid is null
or
select * from tbl where statusid is not null
If your statusid is not null, then it will be selected just fine when you have an actual value, no need for any "if" logic if that is what you were thinking
select * from tbl where statusid = 123 -- the record(s) returned will not have null statusid
if you want to select where it is null or a value, try
select * from tbl where statusid = 123 or statusid is null
It is working fine with me.
I have the following HTML:
<div>
<select id="select1">
<option value="1">test1</option>
<option value="2" selected="selected">test2</option>
<option value="3">test3</option>
</select>
<br/>
<button onClick="GetSelectedItem('select1');">Get Selected Item</button>
</div>
And the following JavaScript:
function GetSelectedItem(el)
{
var e = document.getElementById(el);
var strSel = "The Value is: " + e.options[e.selectedIndex].value + " and text is: " + e.options[e.selectedIndex].text;
alert(strSel);
}
See that you are using the right id. In case you are using it with ASP.NET, the id changes when rendered.
@NielW's answer is the way to go, for real in-place sorting. I wanted to add an slightly altered solution that allows you bypass having to use IComparable
:
static class Extensions
{
public static void Sort<TSource, TKey>(this ObservableCollection<TSource> collection, Func<TSource, TKey> keySelector)
{
List<TSource> sorted = collection.OrderBy(keySelector).ToList();
for (int i = 0; i < sorted.Count(); i++)
collection.Move(collection.IndexOf(sorted[i]), i);
}
}
now you can call it like most any LINQ method:
myObservableCollection.Sort(o => o.MyProperty);
This is step by step process of what worked for me.
First run the app then follow steps below (also shown in screenshot)
When I used it on my Webserver, can I only rename local host, like this:
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mydomain.com [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mydomain.com.*$ [NC]
RewriteRule \.(gif|jpg)$ - [F]
Assuming you already have a application created under google developer console, Follow the below steps
https://console.cloud.google.com/apis/dashboard?
you will be getting the below page Note: Please use a server to load the html
file
Try the above which will run with any list type.
public DataTable ListToDataTable<T>(IList<T> data)
{
PropertyDescriptorCollection props =
TypeDescriptor.GetProperties(typeof(T));
DataTable table = new DataTable();
for (int i = 0; i < props.Count; i++)
{
PropertyDescriptor prop = props[i];
table.Columns.Add(prop.Name, prop.PropertyType);
}
object[] values = new object[props.Count];
foreach (T item in data)
{
for (int i = 0; i < values.Length; i++)
{
values[i] = props[i].GetValue(item);
}
table.Rows.Add(values);
}
return table;
}
How about tree? tree -l
will follow symlinks.
Disclaimer: I wrote this package.
Right now you seem to be saying 'does this array of strings equal this string', which of course it never would.
Perhaps you should think about iterating through your array of strings with a loop, and checking each to see if they are equals() with the inputted string?
...or do I misunderstand your question?
To populate the column during insert, use a DEFAULT
value:
CREATE TABLE users (
id serial not null,
firstname varchar(100),
middlename varchar(100),
lastname varchar(100),
email varchar(200),
timestamp timestamp default current_timestamp
)
Note that the value for that column can explicitly be overwritten by supplying a value in the INSERT
statement. If you want to prevent that you do need a trigger.
You also need a trigger if you need to update that column whenever the row is updated (as mentioned by E.J. Brennan)
Note that using reserved words for column names is usually not a good idea. You should find a different name than timestamp
I prefer to hide all code complexity in my services... so, I generally use something like this:
In my events.service.ts
async getEvents() {
const snapchot = await this.db.collection('events').ref.get();
return new Promise <Event[]> (resolve => {
const v = snapchot.docs.map(x => {
const obj = x.data();
obj.id = x.id;
return obj as Event;
});
resolve(v);
});
}
In my sth.page.ts
myList: Event[];
construct(private service: EventsService){}
async ngOnInit() {
this.myList = await this.service.getEvents();
}
Enjoy :)
If you want to remove the column completely (i.e. not just the button) from the table then use a suitable event handler, e.g. for the OnDataBound
event, and then hide the appropriate column on the target GridView
. Pick an event that will only fire once for this control, i.e. not OnRowDataBound
.
<asp:GridView ID="grdUsers" runat="server" DataSourceID="dsProjectUsers" OnDataBound="grdUsers_DataBound">
<Columns>
<asp:TemplateField HeaderText="Admin Actions">
<ItemTemplate><asp:Button ID="btnEdit" runat="server" text="Edit" /></ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="FirstName" HeaderText="First Name" />
<asp:BoundField DataField="LastName" HeaderText="Last Name" />
<asp:BoundField DataField="Telephone" HeaderText="Telephone" />
</Columns>
</asp:GridView>
protected void grdUsers_DataBound(object sender, EventArgs e)
{
try
{
// in this case hiding the first col if not admin
if (!User.IsInRole(Constants.Role_Name_Admin))
grdUsers.Columns[0].Visible = false;
}
catch (Exception ex)
{
// deal with ex
}
}
=IF(ISNA(INDEX(B:B,MATCH(C2,A:A,0))),"",INDEX(B:B,MATCH(C2,A:A,0)))
Will return the answer you want and also remove the #N/A
result that would appear if you couldn't find a result due to it not appearing in your lookup list.

I've played around with it and I think I have a solution. The following example shows how to set Box-Shadow so that it will only show a shadow for the inset top and bottom of an element.
Legend: insetOption leftPosition topPosition blurStrength spreadStrength color
Description
The key to accomplishing this is to set the blur value to <= the negative of the spread value (ex. inset 0px 5px -?px 5px #000; the blur value should be -5 and lower) and to also keep the blur value > 0 when subtracted from the primary positioning value (ex. using the example from above, the blur value should be -9 and up, thus giving us an optimal value for the the blur to be between -5 and -9).
Solution
.styleName {
/* for IE 8 and lower */
background-color:#888; filter: progid:DXImageTransform.Microsoft.dropShadow(color=#FFFFCC, offX=0, offY=0, positive=true);
/* for IE 9 */
box-shadow: inset 0px 2px -2px 2px rgba(255,255,204,0.7), inset 0px -2px -2px 2px rgba(255,255,204,0.7);
/* for webkit browsers */
-webkit-box-shadow: inset 0px 2px -2px 2px rgba(255,255,204,0.7), inset 0px -2px -2px 2px rgba(255,255,204,0.7);
/* for firefox 3.6+ */
-moz-box-shadow: inset 0px 2px -2px 2px rgba(255,255,204,0.7), inset 0px -2px -2px 2px rgba(255,255,204,0.7);
}
The only way I achieved the "best case" scenario described, was putting the image as a background:
<div class="container"></div>?
.container {
width: 150px;
height: 100px;
background-image: url("http://i.stack.imgur.com/2OrtT.jpg");
background-size: cover;
background-repeat: no-repeat;
background-position: 50% 50%;
}?
I will put a small comparison table here (just to have it somewhere):
Servlet is mapped as /test%3F/*
and the application is deployed under /app
.
http://30thh.loc:8480/app/test%3F/a%3F+b;jsessionid=S%3F+ID?p+1=c+d&p+2=e+f#a
Method URL-Decoded Result
----------------------------------------------------
getContextPath() no /app
getLocalAddr() 127.0.0.1
getLocalName() 30thh.loc
getLocalPort() 8480
getMethod() GET
getPathInfo() yes /a?+b
getProtocol() HTTP/1.1
getQueryString() no p+1=c+d&p+2=e+f
getRequestedSessionId() no S%3F+ID
getRequestURI() no /app/test%3F/a%3F+b;jsessionid=S+ID
getRequestURL() no http://30thh.loc:8480/app/test%3F/a%3F+b;jsessionid=S+ID
getScheme() http
getServerName() 30thh.loc
getServerPort() 8480
getServletPath() yes /test?
getParameterNames() yes [p 2, p 1]
getParameter("p 1") yes c d
In the example above the server is running on the localhost:8480
and the name 30thh.loc
was put into OS hosts
file.
Comments
"+" is handled as space only in the query string
Anchor "#a" is not transferred to the server. Only the browser can work with it.
If the url-pattern
in the servlet mapping does not end with *
(for example /test
or *.jsp
), getPathInfo()
returns null
.
If Spring MVC is used
Method getPathInfo()
returns null
.
Method getServletPath()
returns the part between the context path and the session ID. In the example above the value would be /test?/a?+b
Be careful with URL encoded parts of @RequestMapping
and @RequestParam
in Spring. It is buggy (current version 3.2.4) and is usually not working as expected.
Sometimes you need to first update the apt repo list.
sudo apt-get update
sudo apt purge python2.7-minimal
If you still need to use the HTTP Module you need to configure it (.NET 4.0 framework) as follows:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<add name="MyModule" type="[Namespace].[Class], [assembly]"/>
</modules>
<validation validateIntegratedModeConfiguration="false"/>
</system.webServer>
Okay, another hack with generators:
const value = function* () {_x000D_
let i = 0;_x000D_
while(true) yield ++i;_x000D_
}();_x000D_
_x000D_
Object.defineProperty(this, 'a', {_x000D_
get() {_x000D_
return value.next().value;_x000D_
}_x000D_
});_x000D_
_x000D_
if (a === 1 && a === 2 && a === 3) {_x000D_
console.log('yo!');_x000D_
}
_x000D_
FolderBrowserDialog fbd = new FolderBrowserDialog();
DialogResult result = fbd.ShowDialog();
string[] files = Directory.GetFiles(fbd.SelectedPath);
string[] dirs = Directory.GetDirectories(fbd.SelectedPath);
foreach (string item2 in dirs)
{
FileInfo f = new FileInfo(item2);
listBox1.Items.Add(f.Name);
}
foreach (string item in files)
{
FileInfo f = new FileInfo(item);
listBox1.Items.Add(f.Name);
}
if ([mydict objectForKey:@"mykey"]) {
// key exists.
}
else
{
// ...
}
Not really great but a funny hack: You can -- instead of +
{{num_str -- 1 }}

If you are using sakila-db from mysql website, It's very easy on the Linux platform just follow the below-mentioned steps, After downloading the zip file of sakila-db, extract it. Now you will have two files, one is sakila-schema.sql and the other one is sakila-data.sql.
Please take care that extracted files are present in home directory.
On iOS there is the switch UI component instead of a checkbox, look into the UISwitch
class.
The property on
(boolean) can be used to determine the state of the slider and about the saving of its state: That depends on how you save your other stuff already, its just saving a boolean value.
You need something like this:
foreach(DataColumn c in dr.Table.Columns)
{
MessageBox.Show(c.ColumnName);
}
Another type of solution would be to autogenerate the nginx conf files via Jinja2 templates from ansible. The advantage of this is easy deployment to a cloud environment, and easy to replicate on multiple dev machines
I had a similar problem, nginx was processing a page halfway then stopping. None of the solutions suggested here were working for me. I fixed it by changing nginx fastcgi buffering:
fastcgi_max_temp_file_size 0;
fastcgi_buffer_size 4K;
fastcgi_buffers 64 4k;
After the changes my location
block looked like:
location ~ \.php$ {
try_files $uri /index.php =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_max_temp_file_size 0;
fastcgi_buffer_size 4K;
fastcgi_buffers 64 4k;
include fastcgi_params;
}
For details see https://www.namhuy.net/3120/fix-nginx-upstream-response-buffered-temporary-file-error.html
You can also format the string like so:
>>> print ("{index}. {word} appears {count} times".format(index=1, word='Hello', count=42))
Which outputs
1. Hello appears 42 times.
Because the values are named, their order does not matter. Making the example below output the same as the above example.
>>> print ("{index}. {word} appears {count} times".format(count=42, index=1, word='Hello'))
Formatting string this way allows you to do this.
>>> data = {'count':42, 'index':1, 'word':'Hello'}
>>> print ("{index}. {word} appears {count} times.".format(**data))
1. Hello appears 42 times.
For every PostScript printer, one part of its driver is an ASCII file called PostScript Printer Description (PPD). PPDs are used in the CUPS printing system on Linux and Mac OS X as well even for non-PostScript printers.
Every PPD MUST, according to the PPD specification written by Adobe, contain definitions of a *ImageableArea (that's a PPD keyword) for each and every media sizes it can handle. That value is given for example as *ImageableArea Folio/8,25x13: "12 12 583 923"
for one printer in this office here, and *ImageableArea Folio/8,25x13: "0 0 595 935"
for the one sitting in the next room.
These figures mean "Lower left corner is at (12|12), upper right corner is at (583|923)" (where these figures are measured in points; 72pt == 1inch). Can you see that the first printer does print with a margin of 1/6 inch? -- Can you also see that the next one can even print borderless?
What you need to know is this: Even if the printer can do very small margins physically, if the PPD *ImageableArea
is set to a wider margin, the print data generated by the driver and sent to the printer will be clipped according to the PPD setting -- not by the printer itself.
These days more and more models appear on the market which can indeed print edge-to-edge. This is especially true for office laser printers. (Don't know about devices for the home use market.) Sometimes you have to enable that borderless mode with a separate switch in the driver settings, sometimes also on the device itself (front panel, or web interface).
Older models, for example HP's, define in their PPDs their margines quite generously, just to be on the supposedly "safe side". Very often HP used 1/3, 1/2 inch or more (like "24 24 588 768"
for Letter format). I remember having hacked HP PPDs and tuned them down to "6 6 606 786"
(1/12 inch) before the physical boundaries of the device kicked in and enforced a real clipping of the page image.
Now, PCL and other language printers are not that much different in their margin capabilities from PostScript models.
But of course, when it comes to printing of PDF docs, here you can nearly always choose "print to fit" or similarly named options. Even for a file that itself does not use any margins. That "fit" is what the PDF viewer reads from the driver, and the viewer then scales down the page to the *ImageableArea
.
insert byte to specific place.
insertToArray(arr,index,item) {
return Buffer.concat([arr.slice(0,index),Buffer.from(item,"utf-8"),arr.slice(index)]);
}
try out this if you want to assign value to object and it is showing this error in angular..

You can truncate the date
SELECT *

WHERE trunc(field1) = to_Date('2012-01-01','YYY-MM-DD')
Look at the SQL Fiddle for more examples.
You only need to prefix an if
statement with @
if you're not already inside a razor code block.
Edit: You have a couple of things wrong with your code right now.
You're declaring nmb
, but never actually doing anything with the value. So you need figure out what that's supposed to actually be doing. In order to fix your code, you need to make a couple of tiny changes:
@if (ViewBag.Articles != null)
{
int nmb = 0;
foreach (var item in ViewBag.Articles)
{
if (nmb % 3 == 0)
{
@:<div class="row">
}
<a href="@Url.Action("Article", "Programming", new { id = item.id })">
<div class="tasks">
<div class="col-md-4">
<div class="task important">
<h4>@item.Title</h4>
<div class="tmeta">
<i class="icon-calendar"></i>
@item.DateAdded - Pregleda:@item.Click
<i class="icon-pushpin"></i> Authorrr
</div>
</div>
</div>
</div>
</a>
if (nmb % 3 == 0)
{
@:</div>
}
}
}
The important part here is the @:
. It's a short-hand of <text></text>
, which is used to force the razor engine to render text.
One other thing, the HTML standard specifies that a
tags can only contain inline elements, and right now, you're putting a div
, which is a block-level element, inside an a
.
I know this topic is super old, but, in case if someone's looking for an answer, as me, I'm posting my solution.
This solution works IF you don't mind having some extra data at the beginning of your file.
Basically, the idea is to, if file is not existing, to create it and append current date at the first line.
Next, you can read the first line with fgets(fopen($file, 'r'))
, turn it into a DateTime
object or anything (you can obviously use it raw, unless you saved it in a weird format) and voila - you have your creation date! For example my script to refresh my log file every 30 days looks like this:
if (file_exists($logfile)) {
$now = new DateTime();
$date_created = fgets(fopen($logfile, 'r'));
if ($date_created == '') {
file_put_contents($logfile, date('Y-m-d H:i:s').PHP_EOL, FILE_APPEND | LOCK_EX);
}
$date_created = new DateTime($date_created);
$expiry = $date_created->modify('+ 30 days');
if ($now >= $expiry) {
unlink($logfile);
}
}
With Esc and Command + 1 you can navigate between project view and editor area - back and forward, in this way you can select the folder/location you need
With Control +Option + N you can trigger New file menu and select whatever you need, class, interface, file, etc. This works in editor as well in project view and it relates to the current selected location

I had a problem installing virtualenvwrapper
after successfully installing virtualenv
.
My terminal complained after I did this:
pip install virtualenvwrapper
So, I unsuccessfully tried this (NOT RECOMMENDED):
sudo pip install virtualenvwrapper
Then, I successfully installed it with this:
pip install --user virtualenvwrapper
You can also use regex.
let trimmedString = myString.stringByReplacingOccurrencesOfString("\\s", withString: "", options: NSStringCompareOptions.RegularExpressionSearch, range: nil)
with Scanner
you need to check if there is a next line with hasNextLine()
so the loop becomes
while(sc.hasNextLine()){
str=sc.nextLine();
//...
}
it's readers that return null on EOF
ofcourse in this piece of code this is dependent on whether the input is properly formatted
Nope, there is no way to do this. What you might want to do is however to consider Polymorphism as a way to handle these kind of problems.
Why use getters and setters?

I use WinMerge. It is free and works pretty well (works for files and directories).
You can use a WScript
object and call the Sleep
method on it:
Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds
Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):
Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000
The database does not do joins -- or automatic "linking" between documents. However you can do it yourself client side. If you need to do 2, that is ok, but if you had to do 2000, the number of client/server turnarounds would make the operation slow.
In MongoDB a common pattern is embedding. In relational when normalizing things get broken into parts. Often in mongo these pieces end up being a single document, so no join is needed anyway. But when one is needed, one does it client-side.
Consider the classic ORDER, ORDER-LINEITEM example. One order and 8 line items are 9 rows in relational; in MongoDB we would typically just model this as a single BSON document which is an order with an array of embedded line items. So in that case, the join issue does not arise. However the order would have a CUSTOMER which probably is a separate collection - the client could read the cust_id from the order document, and then go fetch it as needed separately.
There are some videos and slides for schema design talks on the mongodb.org web site I belive.
You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.
After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.
It's incorrect to use zeros in date or in datetime, just put null instead of zeros.
If you using windows, you can fix it via install SVN Tool. If you using Linux/MacOS, you can fix it via install subversion. After that, just select using svn command. Your problems is resolve.
In case you want to have it in your own class:
#include <initializer_list>
Vector<Type>::Vector(std::initializer_list<Type> init_list) : _size(init_list.size()),
_capacity(_size),
_data(new Type[_size])
{
int idx = 0;
for (auto it = init_list.begin(); it != init_list.end(); ++it)
_data[idx++] = *it;
}
spoulson has it nearly right, but you need to create a List<string>
from string[]
first. Actually a List<int>
would be better if uid is also int
. List<T>
supports Contains()
. Doing uid.ToString().Contains(string[])
would imply that the uid as a string contains all of the values of the array as a substring??? Even if you did write the extension method the sense of it would be wrong.
[EDIT]
Unless you changed it around and wrote it for string[]
as Mitch Wheat demonstrates, then you'd just be able to skip the conversion step.
[ENDEDIT]
Here is what you want, if you don't do the extension method (unless you already have the collection of potential uids as ints -- then just use List<int>()
instead). This uses the chained method syntax, which I think is cleaner, and
does the conversion to int to ensure that the query can be used with more providers.
var uids = arrayofuids.Select(id => int.Parse(id)).ToList();
var selected = table.Where(t => uids.Contains(t.uid));
Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.

You can use pd.to_datetime()
to convert to a datetime object. It takes a format parameter, but in your case I don't think you need it.
>>> import pandas as pd
>>> df = pd.DataFrame( {'Symbol':['A','A','A'] ,
'Date':['02/20/2015','01/15/2016','08/21/2015']})
>>> df
Date Symbol
0 02/20/2015 A
1 01/15/2016 A
2 08/21/2015 A
>>> df['Date'] =pd.to_datetime(df.Date)
>>> df.sort('Date') # This now sorts in date order
Date Symbol
0 2015-02-20 A
2 2015-08-21 A
1 2016-01-15 A
For future search, you can change the sort statement:
>>> df.sort_values(by='Date') # This now sorts in date order
Date Symbol
0 2015-02-20 A
2 2015-08-21 A
1 2016-01-15 A
This link helped me a lot for the same problem:
p = ggplot() +
geom_line(data = df_plot, aes(x = idx, y = col1), color = "blue") +
geom_line(data = df_plot, aes(x = idx, y = col2), color = "red")
print(p)
strip
only strips characters from the very front and back of the string.
To delete a list of characters, you could use the string's translate
method:
import string
name = "Barack (of Washington)"
table = string.maketrans( '', '', )
print name.translate(table,"(){}<>")
# Barack of Washington
Check first your class loader.
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
if (classLoader == null) {
classLoader = Class.class.getClassLoader();
}
classLoader.getResourceAsStream("xmlFileNameInJarFile.xml");
// xml file location at xxx.jar
// + folder
// + folder
// xmlFileNameInJarFile.xml
This worked for me
open config.inc.php file in phpmyadmin root, set auth type from cookie to config
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = ''; // leave blank if no password
There are methods to scroll element directly into the view, but if you want to scroll to a point relative from an element, you have to do it manually:
Inside the click handler, get the position of the element relative to the document, subtract 20
and use window.scrollTo
:
var pos = $(this).offset();
var top = pos.top - 20;
var left = pos.left - 20;
window.scrollTo((left < 0 ? 0 : left), (top < 0 ? 0 : top));
I've checked DamienG's answer in LinqPad. Instead of
g.Group.Max(s => s.uid)
should be
g.Max(s => s.uid)
Thank you!
You can use the datetime
module for working with dates and times in Python. The strftime
method allows you to produce string representation of dates and times with a format you specify.
>>> import datetime
>>> datetime.date.today().strftime("%B %d, %Y")
'July 23, 2010'
>>> datetime.datetime.now().strftime("%I:%M%p on %B %d, %Y")
'10:36AM on July 23, 2010'
You need to deserialize the JSON once before returning it as response. Please refer below code. This works for me:
JavaScriptSerializer jss = new JavaScriptSerializer();
Object finalData = jss.DeserializeObject(str);
One nice feature of the Immediate Window in Visual Studio is its ability to evaluate the return value of a method particularly if it is called by your client code but it is not part of a variable assignment. In Debug mode, as mentioned, you can interact with variables and execute expressions in memory which plays an important role in being able to do this.
For example, if you had a static method that returns the sum of two numbers such as:
private static int GetSum(int a, int b)
{
return a + b;
}
Then in the Immediate Window you can type the following:
? GetSum(2, 4)
6
As you can seen, this works really well for static methods. However, if the method is non-static then you need to interact with a reference to the object the method belongs to.
For example, let’s say this is what your class looks like:
private class Foo
{
public string GetMessage()
{
return "hello";
}
}
If the object already exists in memory and it’s in scope, then you can call it in the Immediate Window as long as it has been instantiated before your current breakpoint (or, at least, before wherever the code is paused in debug mode):
? foo.GetMessage(); // object ‘foo’ already exists
"hello"
In addition, if you want to interact and test the method directly without relying on an existing instance in memory, then you can instantiate your own instance in the Immediate Window:
? Foo foo = new Foo(); // new instance of ‘Foo’
{temp.Program.Foo}
? foo.GetMessage()
"hello"
You can take it a step further and temporarily assign the method's results to variables if you want to do further evaluations, calculations, etc.:
? string msg = foo.GetMessage();
"hello"
? msg + " there!"
"hello there!"
Furthermore, if you don’t even want to declare a variable name for a new object and just want to run one of its methods/functions then do this:
? new Foo().GetMessage()
"hello"
A very common way to see the value of a method is to select the method name of a class and do a ‘Add Watch’ so that you can see its current value in the Watch window. However, once again, the object needs to be instantiated and in scope for a valid value to be displayed. This is much less powerful and more restrictive than using the Immediate Window.
Along with inspecting methods, you can do simple math equations:
? 5 * 6
30
or compare values:
? 5==6
false
? 6==6
true
The question mark ('?') is unnecessary if you are in directly in the Immediate Window but it is included here for clarity (to distinguish between the typed in expressions versus the results.) However, if you are in the Command Window and need to do some quick stuff in the Immediate Window then precede your statements with '?' and off you go.
Intellisense works in the Immediate Window, but it sometimes can be a bit inconsistent. In my experience, it seems to be only available in Debug mode, but not in design, non-debug mode.
Unfortunately, another drawback of the Immediate Window is that it does not support loops.
The latest PowerShell version as of Sept 2015 is PowerShell 4.0. It's bundled with Windows Management Framework 4.0.
Here's the download page for PowerShelll 4.0 for all versions of Windows. For Windows 7, there are 2 links on that page, 1 for x64 and 1 for x86.
I've seen issues where some browsers don't respect some changes when you do them directly (by which I mean creating the HTML from text like you're trying with the script tag), but when you do them with built-in commands things go better. Try this:
var script = document.createElement( 'script' );
script.type = 'text/javascript';
script.src = url;
$("#someElement").append( script );

You can go to File -> Preferences -> Keyboard Shortcut. Once you are there, you can search for navigate. Then, you will see all shortcuts set for your VS Code environment related to navigation. In my case, it was only Alt + '-' to get my cursor back.
I think you have to write some extra code. For example:
if 'MICHAEL89' in map(lambda name: name.upper(), USERNAMES):
...
In this case we are forming a new list with all entries in USERNAMES
converted to upper case and then comparing against this new list.
Update
As @viraptor says, it is even better to use a generator instead of map
. See @Nathon's answer.
Not really. Your padding is (probably) being applied to the list item, so will only affect the actual content within the list item.
Using a combination of background and padding styles can create something that looks similar e.g.
li {
background: url(images/bullet.gif) no-repeat left top; /* <-- change `left` & `top` too for extra control */
padding: 3px 0px 3px 10px;
/* reset styles (optional): */
list-style: none;
margin: 0;
}
You might be looking to add styling to the parent list container (ul) to position your bulleted list items, this A List Apart article has a good starting reference.
Your logic is slightly off. The second ||
should be &&
:
if ((!isset($action)) || ($action != "add" && $action != "delete"))
You can see why your original line fails by trying out a sample value. Let's say $action
is "delete"
. Here's how the condition reduces down step by step:
// $action == "delete"
if ((!isset($action)) || ($action != "add" || $action != "delete"))
if ((!true) || ($action != "add" || $action != "delete"))
if (false || ($action != "add" || $action != "delete"))
if ($action != "add" || $action != "delete")
if (true || $action != "delete")
if (true || false)
if (true)
Oops! The condition just succeeded and printed "error", but it was supposed to fail. In fact, if you think about it, no matter what the value of $action
is, one of the two !=
tests will return true. Switch the ||
to &&
and then the second to last line becomes if (true && false)
, which properly reduces to if (false)
.
There is a way to use ||
and have the test work, by the way. You have to negate everything else using De Morgan's law, i.e.:
if ((!isset($action)) || !($action == "add" || $action == "delete"))
You can read that in English as "if action is not (either add or remove), then".
If you don't mind not using ng-click
, it works OK. You can just rename it to something else and still read the attribute, while avoiding the click handler being triggered twice problem there is at the moment.
http://plnkr.co/edit/YWr6o2?p=preview
I think the problem is terminal
instructs other directives not to run. Data-binding with {{ }}
is just an alias for the ng-bind
directive, which is presumably cancelled by terminal
.
you can use cssSelector,
driver.switchTo().frame(driver.findElement(By.cssSelector("iframe[title='Fill Quote']")));
It means:
'O' (Python) objects
The first character specifies the kind of data and the remaining characters specify the number of bytes per item, except for Unicode, where it is interpreted as the number of characters. The item size must correspond to an existing type, or an error will be raised. The supported kinds are to an existing type, or an error will be raised. The supported kinds are:
'b' boolean
'i' (signed) integer
'u' unsigned integer
'f' floating-point
'c' complex-floating point
'O' (Python) objects
'S', 'a' (byte-)string
'U' Unicode
'V' raw data (void)

You can see that your locks are pretty much working as you are using them, if you slow down the process and make them block a bit more. You had the right idea, where you surround critical pieces of code with the lock. Here is a small adjustment to your example to show you how each waits on the other to release the lock.
import threading
import time
import inspect
class Thread(threading.Thread):
def __init__(self, t, *args):
threading.Thread.__init__(self, target=t, args=args)
self.start()
count = 0
lock = threading.Lock()
def incre():
global count
caller = inspect.getouterframes(inspect.currentframe())[1][3]
print "Inside %s()" % caller
print "Acquiring lock"
with lock:
print "Lock Acquired"
count += 1
time.sleep(2)
def bye():
while count < 5:
incre()
def hello_there():
while count < 5:
incre()
def main():
hello = Thread(hello_there)
goodbye = Thread(bye)
if __name__ == '__main__':
main()
Sample output:
...
Inside hello_there()
Acquiring lock
Lock Acquired
Inside bye()
Acquiring lock
Lock Acquired
...
Upgrading from Ubuntu 10.0.4 to 12.0.4 we got wrong footed. We had a JDK installation configured (auto-configured?) pointing to /usr/lib/jvm/java-6-openjdk this no longer contained a JDK, Changing to /usr/lib/jvm/default-java fixed, and should make for a seamless java-7 upgrade.
So in answer to the question: do not specify JAVA_HOME on Ubuntu.
You can use following formulas.
For Excel 2007 or later:
=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")
For Excel 2003:
=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))
Note, that
List!A:C
in VLOOKUP
and returns value from column ? 3
VLOOKUP
equals to FALSE
, in that case VLOOKUP
will only find an exact match, and the values in the first column of List!A:C
do not need to be sorted (opposite to case when you're using TRUE
).To apply it everywhere, you could do something like
$('body').on('click', function() {
if($('.children').is(':visible')) {
$('ul.children').slideUp('slow');
}
});

an alternative to this is Process hacker if you go into run as... (Interactive doesnt work for people with the security enhancments but that wont matter) and when box opens put Service into the box type and put SYSTEM into user box and put C:\Users\Windows\system32\cmd.exe leave the rest click ok and boch you have got a window with cmd on it and run as system now do the other steps for yourself because im suggesting you know them
A ClusterIP exposes the following:
spec.clusterIp:spec.ports[*].port
You can only access this service while inside the cluster. It is accessible from its spec.clusterIp
port. If a spec.ports[*].targetPort
is set it will route from the port to the targetPort. The CLUSTER-IP you get when calling kubectl get services
is the IP assigned to this service within the cluster internally.
A NodePort exposes the following:
<NodeIP>:spec.ports[*].nodePort
spec.clusterIp:spec.ports[*].port
If you access this service on a nodePort from the node's external IP, it will route the request to spec.clusterIp:spec.ports[*].port
, which will in turn route it to your spec.ports[*].targetPort
, if set. This service can also be accessed in the same way as ClusterIP.
Your NodeIPs are the external IP addresses of the nodes. You cannot access your service from spec.clusterIp:spec.ports[*].nodePort
.
A LoadBalancer exposes the following:
spec.loadBalancerIp:spec.ports[*].port
<NodeIP>:spec.ports[*].nodePort
spec.clusterIp:spec.ports[*].port
You can access this service from your load balancer's IP address, which routes your request to a nodePort, which in turn routes the request to the clusterIP port. You can access this service as you would a NodePort or a ClusterIP service as well.
I'd do it this way:
from os.path import abspath, exists
f_path = abspath("fooabar.txt")
if exists(f_path):
with open(f_path) as f:
print f.read()
The above code builds an absolute path to the file using abspath and is equivalent to using normpath(join(os.getcwd(), path))
[that's from the pydocs]. It then checks if that file actually exists and then uses a context manager to open it so you don't have to remember to call close on the file handle. IMHO, doing it this way will save you a lot of pain in the long run.
Check you routes, the update on 9/28/2014 impacted us. We had to adjust our older servers and add new routes. Here is the article http://www.rackspace.com/knowledge_center/article/updating-servicenet-routes-on-cloud-servers-created-before-june-3-2013

Open atom editor and then press Alt and menu bar will appear. Now click on View tab and then click on Toggle Menu Bar as seen on this screenshot.
Use this line to make this work while using the modal:true option.

For those who don't want to create a custom dialog but still prefer a 100% WPF way and don't want to use separate DDLs, additional dependencies or outdated APIs, I came up with a very simple hack using the Save As dialog.
No using directive needed, you may simply copy-paste the code below !
It should still be very user-friendly and most people will never notice.
The idea comes from the fact that we can change the title of that dialog, hide files, and work around the resulting filename quite easily.
It is a big hack for sure, but maybe it will do the job just fine for your usage...
In this example I have a textbox object to contain the resulting path, but you may remove the related lines and use a return value if you wish...
// Create a "Save As" dialog for selecting a directory (HACK)
var dialog = new Microsoft.Win32.SaveFileDialog();
dialog.InitialDirectory = textbox.Text; // Use current value for initial dir
dialog.Title = "Select a Directory"; // instead of default "Save As"
dialog.Filter = "Directory|*.this.directory"; // Prevents displaying files
dialog.FileName = "select"; // Filename will then be "select.this.directory"
if (dialog.ShowDialog() == true) {
string path = dialog.FileName;
// Remove fake filename from resulting path
path = path.Replace("\\select.this.directory", "");
path = path.Replace(".this.directory", "");
// If user has changed the filename, create the new directory
if (!System.IO.Directory.Exists(path)) {
System.IO.Directory.CreateDirectory(path);
}
// Our final value is in path
textbox.Text = path;
}
The only issues with this hack are :
Most people won't notice these, although I would definitely prefer using an official WPF way if microsoft would get their heads out of their asses, but until they do, that's my temporary fix.
Order of magnitude: zero.
In other words, you won't see your throughput cut in half, or anything like it, when you add TLS. Answers to the "duplicate" question focus heavily on application performance, and how that compares to SSL overhead. This question specifically excludes application processing, and seeks to compare non-SSL to SSL only. While it makes sense to take a global view of performance when optimizing, that is not what this question is asking.
The main overhead of SSL is the handshake. That's where the expensive asymmetric cryptography happens. After negotiation, relatively efficient symmetric ciphers are used. That's why it can be very helpful to enable SSL sessions for your HTTPS service, where many connections are made. For a long-lived connection, this "end-effect" isn't as significant, and sessions aren't as useful.
Here's an interesting anecdote. When Google switched Gmail to use HTTPS, no additional resources were required; no network hardware, no new hosts. It only increased CPU load by about 1%.
Is there a prize for being lazy and using the transpose function of NumPy arrays? ;)
import numpy as np
a = np.array([(1,2,3), (4,5,6)])
b = a.transpose()
You can use word-wrap : break-word;
With Recent Symfony 2.6+ versions as a best practice Request is passed as an argument with action in that case you won't need to explicitly call $this->getRequest(), but rather call $request->request->all()
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

Just right click on the project name and select Android tools and click Rename Application Package name and rename it. It's only for Android projects.
private static void replaceChar() {
String str = "hello world";
final String[] res = Arrays.stream(str.split(""))
.filter(s -> !s.equalsIgnoreCase("o"))
.toArray(String[]::new);
System.out.println(String.join("", res));
}
In case you have some complicated logic to filter the char, just another way instead of replace()
.
The high scoring answer above nailed it.
First you were mixing base 2 and base 10 in your question, then when you put a number on the right side that is not divisible into the base you get problems. Like 1/3 in decimal because 3 doesnt go into a power of 10 or 1/5 in binary which doesnt go into a power of 2.
Another comment though NEVER use equal with floating point numbers, period. Even if it is an exact representation there are some numbers in some floating point systems that can be accurately represented in more than one way (IEEE is bad about this, it is a horrible floating point spec to start with, so expect headaches). No different here 1/3 is not EQUAL to the number on your calculator 0.3333333, no matter how many 3's there are to the right of the decimal point. It is or can be close enough but is not equal. so you would expect something like 2*1/3 to not equal 2/3 depending on the rounding. Never use equal with floating point.
On Windows and Linux, press Ctrl+K, then release the keys and press O (the letter O, not Zero).
On macOS, press command+K, then O (without holding command).
This will open the active file tab in a new window/instance.
In python, bool(sequence)
is False
if the sequence is empty. Since strings are sequences, this will work:
cookie = ''
if cookie:
print "Don't see this"
else:
print "You'll see this"
There is a way to use guards for individual (or multiple) attributes.
@debug: true;
header {
/* guard for attribute */
& when (@debug = true) {
background-color: yellow;
}
/* guard for nested class */
#title when (@debug = true) {
background-color: orange;
}
}
/* guard for class */
article when (@debug = true) {
background-color: red;
}
/* and when debug is off: */
article when not (@debug = true) {
background-color: green;
}
...and with Less 1.7; compiles to:
header {
background-color: yellow;
}
header #title {
background-color: orange;
}
article {
background-color: red;
}
Approach i used some years ago -
We need a jsp file , a servlet java file and a filter java file.
Give access of jsp file to user. User type url of jsp file .
Case 1 -
Using Printwriter , it will render the response to user .
Meanwhile, Servlet will create a key file .
When servlet try to execute the xxxx.js file within it , Filter
will activate and will detect key file exist and hence delete key
file .
Thus one cycle is over.
In short ,key file will created by server and will be immediatly deleted by filter .
This will happen upon every hit .
Case 2 -
Instead of File creation , one may use setting value in session variable .
multipart/form-data
is used when you want to upload files to the server. Please check this article for details.
I do this a lot. A lot. :-)
I have got used to using "DoEvents" more often, but still tend to set things running without really double checking a sure stop method.
Then, today, having done it again, I thought, "Well just wait for the end in 3 hours", and started paddling around in the ribbon. Earlier, I had noticed in the "View" section of the Ribbon a "Macros" pull down, and thought I have a look to see if I could see my interminable Macro running....
I now realise you can also get this up using Alt-F8.
Then I thought, well what if I "Step into" a different Macro, would that rescue me? It did :-) It also works if you step into your running Macro (but you still lose where you're upto), unless you are a very lazy programmer like me and declare lots of "Global" variables, in which case the Global data is retained :-)

Developer Key = Api Key (any of yours)

Just like ASP.NET variant, except put the hidden input with the same name before the actual checkbox (of the same name). Only last values will be sent. This way if a box is checked then its name and value "on" is sent, whereas if it's unchecked then the name of the corresponding hidden input and whatever value you might like to give it will be sent. In the end you will get the $_POST array to read, with all checked and unchecked elements in it, "on" and "false" values, no duplicate keys. Easy to process in PHP.
Use the -ExpandProperty
flag of Select-Object
$var=Get-WSManInstance -enumerate wmicimv2/win32_process | select -expand Priority
Update to answer the other question:
Note that you can as well just access the property:
$var=(Get-WSManInstance -enumerate wmicimv2/win32_process).Priority
So to get multiple of these into variables:
$var=Get-WSManInstance -enumerate wmicimv2/win32_process
$prio = $var.Priority
$pid = $var.ProcessID
As long as the macros in question are in the same workbook and you verify the names exist, you can call those macros from any other module by name, not by module.
So if in Module1 you had two macros Macro1 and Macro2 and in Module2 you had Macro3 and Macro 4, then in another macro you could call them all:
Sub MasterMacro()
Call Macro1
Call Macro2
Call Macro3
Call Macro4
End Sub
You probably want kbhit();
//Example will loop until a key is pressed
#include <conio.h>
#include <iostream>
using namespace std;
int main()
{
while(1)
{
if(kbhit())
{
break;
}
}
}
this may not work on all environments. A portable way would be to create a monitoring thread and set some flag on getch();
Try it, it will work for any number of substrings
<?php
$string = 'bcadef abcdef';
$substr = 'a';
$attachment = '+++';
//$position = strpos($string, 'a');
$newstring = str_replace($substr, $substr.$attachment, $string);
// bca+++def a+++bcdef
?>
Simply pass latitude, longitude and your Google API Key to the following query string, you will get a json array, fetch your city from there.
https://maps.googleapis.com/maps/api/geocode/json?latlng=44.4647452,7.3553838&key=YOUR_API_KEY
Note: Ensure that no space exists between the latitude and longitude values when passed in the latlng parameter.
You get this error if you have constrained T

This will remove ALL (white)-space, leading, trailing and within the string.
Store.getRange()
seems to be exactly what you are searching for. It will return you Ext.data.Record[]
- array of records. If no arguments is passed, all the records are returned.
Only if you are targeting webkit-based browsers (Chrome and Safari, maybe you are developing a Chrome WebApp, who knows...), you can use the following:
input[type='radio'] {
-webkit-appearance: none;
}
And then style it as if it were a simple HTML element, for example applying a background image.
Use input[type='radio']:active
for when the input is selected, to provide the alternate graphics
Update: As of 2018 you can add the following to support multiple browser vendors:
input[type="radio"] {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}
In Python we use csv.writer() module to write data into csv files. This module is similar to the csv.reader() module.
import csv
person = [['SN', 'Person', 'DOB'],
['1', 'John', '18/1/1997'],
['2', 'Marie','19/2/1998'],
['3', 'Simon','20/3/1999'],
['4', 'Erik', '21/4/2000'],
['5', 'Ana', '22/5/2001']]
csv.register_dialect('myDialect',
delimiter = '|',
quoting=csv.QUOTE_NONE,
skipinitialspace=True)
with open('dob.csv', 'w') as f:
writer = csv.writer(f, dialect='myDialect')
for row in person:
writer.writerow(row)
f.close()
A delimiter is a string used to separate fields. The default value is comma(,).
I was also wondering about the performance issue, and was hoping this would be optimised out by the compiler, based on the answer from @EmileCormier. However, I was worried that the test code he showed would still allow the compiler to optimise away the std::pow() call, since the same values were used in the call every time, which would allow the compiler to store the results and re-use it in the loop - this would explain the almost identical run-times for all cases. So I had a look into it too.
Here's the code I used (test_pow.cpp):
#include <iostream>
#include <cmath>
#include <chrono>
class Timer {
public:
explicit Timer () : from (std::chrono::high_resolution_clock::now()) { }
void start () {
from = std::chrono::high_resolution_clock::now();
}
double elapsed() const {
return std::chrono::duration_cast<std::chrono::milliseconds>(std::chrono::high_resolution_clock::now() - from).count() * 1.0e-6;
}
private:
std::chrono::high_resolution_clock::time_point from;
};
int main (int argc, char* argv[])
{
double total;
Timer timer;
total = 0.0;
timer.start();
for (double i = 0.0; i < 1.0; i += 1e-8)
total += std::pow (i,2);
std::cout << "std::pow(i,2): " << timer.elapsed() << "s (result = " << total << ")\n";
total = 0.0;
timer.start();
for (double i = 0.0; i < 1.0; i += 1e-8)
total += i*i;
std::cout << "i*i: " << timer.elapsed() << "s (result = " << total << ")\n";
std::cout << "\n";
total = 0.0;
timer.start();
for (double i = 0.0; i < 1.0; i += 1e-8)
total += std::pow (i,3);
std::cout << "std::pow(i,3): " << timer.elapsed() << "s (result = " << total << ")\n";
total = 0.0;
timer.start();
for (double i = 0.0; i < 1.0; i += 1e-8)
total += i*i*i;
std::cout << "i*i*i: " << timer.elapsed() << "s (result = " << total << ")\n";
return 0;
}
This was compiled using:
g++ -std=c++11 [-O2] test_pow.cpp -o test_pow
Basically, the difference is the argument to std::pow() is the loop counter. As I feared, the difference in performance is pronounced. Without the -O2 flag, the results on my system (Arch Linux 64-bit, g++ 4.9.1, Intel i7-4930) were:
std::pow(i,2): 0.001105s (result = 3.33333e+07)
i*i: 0.000352s (result = 3.33333e+07)
std::pow(i,3): 0.006034s (result = 2.5e+07)
i*i*i: 0.000328s (result = 2.5e+07)
With optimisation, the results were equally striking:
std::pow(i,2): 0.000155s (result = 3.33333e+07)
i*i: 0.000106s (result = 3.33333e+07)
std::pow(i,3): 0.006066s (result = 2.5e+07)
i*i*i: 9.7e-05s (result = 2.5e+07)
So it looks like the compiler does at least try to optimise the std::pow(x,2) case, but not the std::pow(x,3) case (it takes ~40 times longer than the std::pow(x,2) case). In all cases, manual expansion performed better - but particularly for the power 3 case (60 times quicker). This is definitely worth bearing in mind if running std::pow() with integer powers greater than 2 in a tight loop...
Eclipse has an option to format automatically when saving the file. There is no option for this in IntelliJ although you can configure a macro for the Ctrl+S (Cmd+S on Mac) keys to format the code and save it.
Try adding whatever's missing to the global assembly cache.
There is no such limit on the string length. To be certain, I just tested to create a string containing 60 megabyte.
The problem is likely that you are sending the data in a GET request, so it's sent in the URL. Different browsers have different limits for the URL, where IE has the lowest limist of about 2 kB. To be safe, you should never send more data than about a kilobyte in a GET request.
To send that much data, you have to send it in a POST request instead. The browser has no hard limit on the size of a post, but the server has a limit on how large a request can be. IIS for example has a default limit of 4 MB, but it's possible to adjust the limit if you would ever need to send more data than that.
Also, you shouldn't use += to concatenate long strings. For each iteration there is more and more data to move, so it gets slower and slower the more items you have. Put the strings in an array and concatenate all the items at once:
var items = $.map(keys, function(item, i) {
var value = $("#value" + (i+1)).val().replace(/"/g, "\\\"");
return
'{"Key":' + '"' + Encoder.htmlEncode($(this).html()) + '"' + ",'+
'" + '"Value"' + ':' + '"' + Encoder.htmlEncode(value) + '"}';
});
var jsonObj =
'{"code":"' + code + '",'+
'"defaultfile":"' + defaultfile + '",'+
'"filename":"' + currentFile + '",'+
'"lstResDef":[' + items.join(',') + ']}';
I did the following to add a role 'eSumit' on PostgreSQL 9.4.15 database and provide all permission to this role :
CREATE ROLE eSumit;
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO eSumit;
GRANT ALL PRIVILEGES ON DATABASE "postgres" to eSumit;
ALTER USER eSumit WITH SUPERUSER;
Also checked the pg_table enteries via :
int mid = 10;
for (double j = 2 * mid; j >= 0; j = j - 0.1) {
if (j == mid) {
System.out.println("Never happens"); // is NOT printed
}
if (Double.compare(j, mid) == 0) {
System.out.println("No way!"); // is NOT printed
}
if (Math.abs(j - mid) < 1e-6) {
System.out.println("Ha!"); // printed
}
}
System.out.println("Gotcha!");
Here's my standard implementation. I like the labels to be self-descriptive.
Public Sub DoSomething()
On Error GoTo Catch ' Try
' normal code here
Exit Sub
Catch:
'error code: you can get the specific error by checking Err.Number
End Sub
Or, with a Finally
block:
Public Sub DoSomething()
On Error GoTo Catch ' Try
' normal code here
GoTo Finally
Catch:
'error code
Finally:
'cleanup code
End Sub
You need to call OS-specific functions for filesystem traversal, like open()
and readdir()
. The C standard does not specify any filesystem-related functions.
Here is an example of how you do it with expect
tool:
sub copyover {
$scp = Expect->spawn("/usr/bin/scp ${srcpath}/$file $who:${destpath}/$file");
$scp->expect(30,"ssword: ") || die "Never got password prompt from $dest:$!\n";
print $scp 'password' . "\n";
$scp->expect(30,"-re",'$\s') || die "Never got prompt from parent system:$!\n";
$scp->soft_close();
return;
}
Be careful when using an IDE's code-completion to add the import for @Test
.
It has to be import org.junit.Test
and not import org.testng.annotations.Test
, for example. If you do the latter, you'll get the "no runnable methods" error.
Following is another way of doing it using plain PHP without the information_schema database:
$chkcol = mysql_query("SELECT * FROM `my_table_name` LIMIT 1");
$mycol = mysql_fetch_array($chkcol);
if(!isset($mycol['my_new_column']))
mysql_query("ALTER TABLE `my_table_name` ADD `my_new_column` BOOL NOT NULL DEFAULT '0'");
You can download a JSON parser from a link on the JSON.org website which works great, you can also stringify you JSON to view the contents.
Also, if you're using EVAL and it's a JSON array then you'll need to use the following synrax:
eval('([' + jsonData + '])');
This one works for me (Swift UI)
struct DetailView: View {
@Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
var body: some View {
VStack {
Text("This is the detail view")
Button(action: {
self.presentationMode.wrappedValue.dismiss()
}) {
Text("Back")
}
}
}
}
Server is trying to read data from the request, but its taking longer than the timeout value for the data to arrive from the client. Timeout here would typically be tomcat connector -> connectionTimeout attribute.
Correct.
Client has a read timeout set, and server is taking longer than that to respond.
No. That would cause a timeout at the client.
One of the threads i went through, said this can happen with high concurrency and if the keepalive is enabled.
That is obviously guesswork, and completely incorrect. It happens if and only if no data arrives within the timeout. Period. Load and keepalive and concurrency have nothing to do with it whatsoever.
It just means the client isn't sending. You don't need to worry about it. Browser clients come and go in all sorts of strange ways.
All the answers are pointing to a Lambda expression with an NRE (Null Reference Exception). I have found that it also occurs when using Linq to Entities. I thought it would be helpful to point out that this exception is not limited to just an NRE inside a Lambda expression.
You will get this warning if you are using npm v6 or before. After npm v7.0, npm development team has stated that they will automatically install peer dependencies, all together. Therefore, now you don't want to install your peer dependencies manually.
You can install npm v7.0 using this command,
npm install -g npm@7
Learn more about npm v7.0 from this blog post, published by the Github Blog.
None of those answers include a counter...
#!/bin/bash
## declare an array variable
declare -a array=("one" "two" "three")
# get length of an array
arraylength=${#array[@]}
# use for loop to read all values and indexes
for (( i=1; i<${arraylength}+1; i++ ));
do
echo $i " / " ${arraylength} " : " ${array[$i-1]}
done
Output:
1 / 3 : one

3 / 3 : three
It's not working because console.log() it's not in a "executable area" of the class "App".
A class is a structure composed by attributes and methods.
The only way to have your code executed is to place it inside a method that is going to be executed. For instance: constructor()
console.log('It works here')_x000D_
_x000D_
@Component({..)_x000D_
export class App {_x000D_
s: string = "Hello2";_x000D_
_x000D_
constructor() {_x000D_
console.log(this.s) _x000D_
} _x000D_
}
_x000D_
Think of class like a plain javascript object.
Would it make sense to expect this to work?
class: {_x000D_
s: string,_x000D_
console.log(s)_x000D_
}
_x000D_
If you still unsure, try the typescript playground where you can see your typescript code generated into plain javascript.
There isn't an element on your page with the id "mainContent" when your callback is being executed.
In the line:
document.getElementById("mainContent").appendChild(p);
the section document.getElementById("mainContent")
is returning null

I nearly used everything in that article to create the SQLite database for my own C# Application.
Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.
After you added the reference, refer to the dll from your code using the following line on top of your class:
using System.Data.SQLite;
You can find the dll's here:
You can find the NuGet way here:
Up next is the create script. Creating a database file:
SQLiteConnection.CreateFile("MyDatabase.sqlite");
SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();
string sql = "create table highscores (name varchar(20), score int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
sql = "insert into highscores (name, score) values ('Me', 9001)";
command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
m_dbConnection.Close();
After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.
Example on how to use transactions:
using (TransactionScope tran = new TransactionScope())
{
//Insert create script here.
//Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
tran.Complete();
}

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.
On the face of it, it looks okay - if you call eraseCookie()
on each cookie that is read from document.cookie
, then all of your cookies will be gone.
Try this:
var cookies = document.cookie.split(";");
for (var i = 0; i < cookies.length; i++)
eraseCookie(cookies[i].split("=")[0]);
All of this with the following caveat:
In my case, it was because I was trying to setup django-environ
and I missed an important step:
Note: In the instructions below .env.example and .env should be saved in the same folder as settings.py
I incorrectly assumed that .env
belonged in the root of my project. Moving it to the same folder as settings.py
fixed the problem.
This error message in the Python console was the clue that set me on the right path:
Warning: /Users/allen/PycharmProjects/myapp/myapp/.env doesn't exist - if you're not configuring your environment separately, create one.
This statement will definitely help you:
env = env.OrderByDescending(c => c.ReportDate).ToList();
You can use the following method in a util class, and use it whenever necessary...
public static List<String> readLinesFromGZ(String filePath) {
List<String> lines = new ArrayList<>();
File file = new File(filePath);
try (GZIPInputStream gzip = new GZIPInputStream(new FileInputStream(file));
BufferedReader br = new BufferedReader(new InputStreamReader(gzip));) {
String line = null;
while ((line = br.readLine()) != null) {
lines.add(line);
}
} catch (FileNotFoundException e) {
e.printStackTrace(System.err);
} catch (IOException e) {
e.printStackTrace(System.err);
}
return lines;
}
You should use only one mediaplayer object
public class PlayaudioActivity extends Activity {
private MediaPlayer mp;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b = (Button) findViewById(R.id.button1);
Button b2 = (Button) findViewById(R.id.button2);
final TextView t = (TextView) findViewById(R.id.textView1);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);
mp.start();
}
});
b2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
stopPlaying();
mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);
mp.start();
}
});
}
private void stopPlaying() {
if (mp != null) {
mp.stop();
mp.release();
mp = null;
}
}
}
Another and easy way using cat command
cat filename | awk '{print $2,$3,$4,$5,$6,$1}' > newfilename
keras predict_classes (docs) outputs A numpy array of class predictions. Which in your model case, the index of neuron of highest activation from your last(softmax) layer. [[0]]
means that your model predicted that your test data is class 0. (usually you will be passing multiple image, and the result will look like [[0], [1], [1], [0]]
)
You must convert your actual label (e.g. 'cancer', 'not cancer'
) into binary encoding (0
for 'cancer', 1
for 'not cancer') for binary classification. Then you will interpret your sequence output of [[0]]
as having class label 'cancer'
The -Wl,xxx
option for gcc passes a comma-separated list of tokens as a space-separated list of arguments to the linker. So
gcc -Wl,aaa,bbb,ccc
eventually becomes a linker call
ld aaa bbb ccc
In your case, you want to say "ld -rpath .
", so you pass this to gcc as -Wl,-rpath,.
Alternatively, you can specify repeat instances of -Wl
:
gcc -Wl,aaa -Wl,bbb -Wl,ccc
Note that there is no comma between aaa
and the second -Wl
.
Or, in your case, -Wl,-rpath -Wl,.
.
Declare separate functions in the <head> section and invoke those in your onClick method. If you have lots you could use a naming scheme that numbers them, or pass an integer in in your onClicks and have a big fat switch statement in the function.
Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.
First, click Slide Show > Set Up Show.
Put a checkmark to Loop continuously until 'Esc'.
Click Ok. Now, Click Slide Show > Custom Shows. Click New.
Select the slide you are looping, click Add. Click Ok and Close.
Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.
Right click on the thumbnail of the current slide, select Hide Slide.
Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"
This has worked for me.
I think you can make this work using jQuery's .on event handler.

Although this post is 6 years old now, however, a lot has changed in the Junit world. With Junit5, you can now use
org.junit.jupiter.api.Assertions.assertDoesNotThrow()
Ex:
public void thisMethodDoesNotThrowException(){
System.out.println("Hello There");
}
@Test
public void test_thisMethodDoesNotThrowException(){
org.junit.jupiter.api.Assertions.assertDoesNotThrow(
()-> thisMethodDoesNotThrowException()
);
}
Hope it will help people who are using newer version of Junit5
Here is email code I used in one of my databases. I just made variables for the person I wanted to send it to, CC, subject, and the body. Then you just use the DoCmd.SendObject command. I also set it to "True" after the body so you can edit the message before it automatically sends.
Public Function SendEmail2()
Dim varName As Variant
Dim varCC As Variant
Dim varSubject As Variant
Dim varBody As Variant
varName = "[email protected]"
varCC = "[email protected], [email protected]"
'separate each email by a ','
varSubject = "Hello"
'Email subject
varBody = "Let's get ice cream this week"
'Body of the email
DoCmd.SendObject , , , varName, varCC, , varSubject, varBody, True, False
'Send email command. The True after "varBody" allows user to edit email before sending.
'The False at the end will not send it as a Template File
End Function
In some cases, you need to force refresh the view in order to make it work.

He're the full migration for Laravel 5:
public function up()
{
Schema::table('users', function (Blueprint $table) {
$table->unsignedInteger('user_id')->nullable()->change();
});
}
public function down()
{
Schema::table('users', function (Blueprint $table) {
$table->unsignedInteger('user_id')->nullable(false)->change();
});
}
The point is, you can remove nullable
by passing false
as an argument.
What Jeremiah said, plus the compiler issues the warning because the production:
*src ="anotherstring";
says: take the address of "anotherstring" -- "anotherstring" IS a char pointer -- and store that pointer indirect through src (*src = ... ) into the first char of the string "abcdef..." The warning might be baffling because there is nowhere in your code any mention of any integer: the warning seems nonsensical. But, out of sight behind the curtain, is the rule that "int" and "char" are synonymous in terms of storage: both occupy the same number of bits. The compiler doesn't differentiate when it issues the warning that you are storing into an integer. Which, BTW, is perfectly OK and legal but probably not exactly what you want in this code.

C - an older programming language that is described as Hands-on. As the programmer you must tell the program to do everything. Also this language will let you do almost anything. It does not support object orriented code. Thus no classes.
C++ - an extention language per se of C. In C code ++ means increment 1. Thus C++ is better than C. It allows for highly controlled object orriented code. Once again a very hands on language that goes into MUCH detail.
C# - Full object orriented code resembling the style of C/C++ code. This is really closer to JAVA. C# is the latest version of the C style languages and is very good for developing web applications.
You can use the call
command...
Type: call /?
Usage: call [drive:][path]filename [batch-parameters]
For example call "Example File/Input File/My Program.bat"
[This is also capable with calling files that have a .exe, .cmd, .txt, etc.
NOTE: THIS COMMAND DOES NOT ALWAYS WORK!!!
Not all computers are capable to run this command, but if it does work than it is very useful, and you won't have to open a brand new window...

oneHr:=3600

You can use the ThenBy and ThenByDescending extension methods:

Yes, you can detect if the session is already running by checking isset($_SESSION)
. However the best answer is simply not to call session_start()
more than once.
It should be called very early in your script, possibly even the first line, and then not called again.
If you have it in more than one place in your code then you're asking to get this kind of bug. Cut it down so it's only in one place and can only be called once.

function scrollToBottom (id) {
var div = document.getElementById(id);
div.scrollTop = div.scrollHeight - div.clientHeight;

var div = document.getElementById(id);
$('#' + id).animate({
scrollTop: div.scrollHeight - div.clientHeight
}, 500);
}

It seems to be true so far. The only SDK available from Apple only targets the macOS environment. I've been upset about that, but I'm looking into buying a mac now, just to do iPhone development. I really dislike what they are doing, and I hope a good SDK come out for other environments, such as Linux and Windows.
Obstacles regarding the SDK:
The iPhone SDK and free software: not a match
Apple's recently released a software development kit (SDK) for the iPhone, but if you were hoping to port or develop original open source software with it, the news isn't good. Code signing and nondisclosure conditions make free software a no-go.
The SDK itself is a free download, with which you can write programs and run them on a software simulator. But in order to actually release software you've written, you must enroll in the iPhone Developer Program -- a step separate from downloading the SDK, and one that requires Apple's approval.
I think it's rather elitist for them to think only macOS users are good enough to write programs for their phone, and the fact you need to buy a $100 license if you want to publish your stuff, really makes it more difficult for the hobbyist programmer. Though, if that's what you need to do, I'm planning on jumping through their hoops; I'd really like to get some stuff developed on my iPhone.
The easiest might be:
Array(1, 2, 3) :+ 4

Xcode Workspace vs Project
- What is the difference between the two of them?
Workspace
is a set of projects
- What are they responsible for?
Workspace
is responsible for dependencies between projects.
Project
is responsible for the source code.
- Which one of them should I work with when I'm developing my Apps in team/alone?
You choice should depends on a type of your project. For example if your project relies on CocoaPods dependency manager it creates a workspace.
- Is there anything else I should be aware of in matter of these two files?
A competitor of workspace is cross-project references

In GitHub Wiki markdown I used hash marks (#) followed by two spaces to make the line break larger. It doesn't actually give you multiple line breaks but it made one large line break and served me well for my needs.
Instead of:

more text
I did:
text
(hash mark)(space)(space)
more text

I use your exact proposed code with only some few additional lines. The idea is more or less the same of the one proposed by @elias, but in this solution there cannot be conflicts on the keys since each file in the directory has a different filename and so adding it to the key solves the conflicts. The first part of the key is the datetime string formatted in a manner such that I can lexicographically compare two of them.
if ($handle = opendir('.')) {
$result = array();
while (false !== ($file = readdir($handle))) {

if(strlen($file)-strpos($file,".swf")== 4){
$result [date('Y-m-d H:i:s',filemtime($file)).$file] =
"<tr><td><input type=\"checkbox\" name=\"box[]\"></td><td><a href=\"$file\" target=\"_blank\">$file</a></td><td>$lastModified</td></tr>";

If you are using the latest version of Visual Studio Code (version 1.21.1). The task.json
format has changed, see here. So the answer by Fenton and by python_starter may no longer be valid.
Before you start configuring Visual Studio Code for running your Python file.
File -> Open Folder
to set your working folder).Now you can configure the task. The following steps will help you run your python file correctly:
task
, you will see a list of options, select Tasks: Configure Task
.create task.json from template
, choose this option, and you will be prompted to choose from a list of options. Choose Others
.Then in the opened task.json
file, use the following settings:
{
"version": "2.0.0",
"tasks": [
{
"label": "run this script",
"type": "shell",
"command": "python",
"args": [
"${file}"
],
"problemMatcher": []
}
]
}
In the above settings, you can give a meaningful label
to this task. For example, run python
.
Tasks
menu and click Run Task
. You will be prompted to choose the task. Just choose the newly created run this script
task. You will see the result in the TERMINAL
tab.For a more complete tutorial about task configuration, go to the Visual Studio Code official documentation.

folder of my project. It worked well. (My computer is 64-bit version)
Dispose(true);
GC.SuppressFinalize(this);
If object has finalizer, .net put a reference in finalization queue.
Since we have call Dispose(ture)
, it clear object, so we don't need finalization queue to do this job.
So call GC.SuppressFinalize(this)
remove reference in finalization queue.
You can't. The -c switch tells you when the permissions were last changed, -a tests the most recent access time, and -m tests the modification time. The filesystem used by most flavors of Linux (ext3) doesn't support a "creation time" record. Sorry!
The mappedBy
attribute is referencing customer
while the property is mCustomer
, hence the error message. So either change your mapping into:
/** The collection of stores. */
@OneToMany(mappedBy = "mCustomer", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
private Collection<Store> stores;
Or change the entity property into customer
(which is what I would do).
The mappedBy reference indicates "Go look over on the bean property named 'customer' on the thing I have a collection of to find the configuration."
As Toan suggests, a simple hack would be to just select the rows first, and then select the columns over that.
>>> a[[0,1,3], :] # Returns the rows you want
array([[ 0, 1, 2, 3],
[ 4, 5, 6, 7],
[12, 13, 14, 15]])
>>> a[[0,1,3], :][:, [0,2]] # Selects the columns you want as well
array([[ 0, 2],
[ 4, 6],
[12, 14]])
np.ix_
I recently discovered that numpy gives you an in-built one-liner to doing exactly what @Jaime suggested, but without having to use broadcasting syntax (which suffers from lack of readability). From the docs:
Using ix_ one can quickly construct index arrays that will index the cross product.
a[np.ix_([1,3],[2,5])]
returns the array[[a[1,2] a[1,5]], [a[3,2] a[3,5]]]
.
So you use it like this:
>>> a = np.arange(20).reshape((5,4))
>>> a[np.ix_([0,1,3], [0,2])]
array([[ 0, 2],
[ 4, 6],
[12, 14]])
And the way it works is that it takes care of aligning arrays the way Jaime suggested, so that broadcasting happens properly:
>>> np.ix_([0,1,3], [0,2])
(array([[0],
[1],
[3]]), array([[0, 2]]))
Also, as MikeC says in a comment, np.ix_
has the advantage of returning a view, which my first (pre-edit) answer did not. This means you can now assign to the indexed array:
>>> a[np.ix_([0,1,3], [0,2])] = -1
>>> a
array([[-1, 1, -1, 3],
[-1, 5, -1, 7],
[ 8, 9, 10, 11],
[-1, 13, -1, 15],
[16, 17, 18, 19]])
